Definitions

  • the invention relates to a method for controlling a vehicle three-phase generator according to the preamble of the main claim.
  • a method for controlling a vehicle three-phase generator according to the preamble of the main claim is known from EP-A-0 210 819
  • Three-phase generators are preferably used today to supply power to the motor vehicle. These generators generate an alternating voltage or an alternating current, which is rectified in a rectifier arrangement connected downstream of the generator and is used to supply the consumers and to charge the battery. Since the output voltage of the three-phase generator depends considerably on the generator speed, a voltage regulator must be used to achieve the desired constant output voltage.
  • the voltage regulator influences the generator excitation current in such a way that the generator output voltage maintains a constant value, for example 14 volts, in spite of the generator speed changing considerably between idling and full load and despite considerable load fluctuations of the generator.
  • a voltage regulator for a generator which charges a battery in a motor vehicle.
  • the temperature of this battery is measured with a temperature sensor, and a voltage proportional to the battery temperature is fed to the controller. It is further provided to provide internal temperature detection in the voltage regulator itself, which is then used to regulate the generator output voltage if the battery temperature sensor has a defect. Taking the battery temperature or the regulator temperature into account even when regulating the voltage enables an improvement in the charge balance by increasing the generator output voltage, especially at low temperatures.
  • the invention is therefore based on the object of regulating a vehicle three-phase generator in such a way that, taking into account the strongly fluctuating generator speed, it enables optimum power output and is nevertheless protected against thermal overload.
  • the method according to the invention for regulating the voltage of a vehicle alternator has the advantage over the known that the generator can be operated in an overexcited area if large power output is required, so that it delivers the maximum possible power, at the same time it is prevented that the generator is destroyed due to thermal overheating. Since the temperature measurement takes place in the voltage regulator itself and since the voltage regulator is fastened to the connecting plate of the rectifier, it is ensured that the temperature relevant for the thermal load is measured by direct coupling.
  • the generator can be operated in the overexcited range until the temperature reaches a critical value. Subsequent reduction of the excitation current ensures that the temperature of the generator or the controller drops again.
  • FIG. 1 shows the profile of the generator output current, the diode temperature and the excitation current over the generator speed for a constant output voltage of the generator.
  • FIG. 2 shows a vehicle three-phase generator and
  • FIG. 3 shows a schematic block diagram of an electrical circuit, from which the known circuit connections between the controller, battery and three-phase generator with their essential structural components emerge.
  • FIG. 1 shows a diagram which shows the basic course of the generator output current I Gen and the diode temperature T over the generator speed for a constant output voltage of the generator.
  • the solid lines are valid at constant excitation current I err .
  • the temperature assumes inadmissibly high values if the excitation current I err is selected to be higher than the nominal excitation current of the generator, or if, for example, there is a high ambient temperature, it is therefore proposed according to the invention to reduce the excitation current so far in this speed range that the temperature takes the course shown in dashed lines in Figure 1.
  • the associated excitation current in the range between n1 and n2 is also shown in dashed lines.
  • the generator current will also increase somewhat more slowly in this area, for example it will take the course shown in dashed lines in FIG.
  • the speed range n1 ⁇ n ⁇ n2, in which the diode temperature is too high can not be easily determined in advance, as it is influenced by external influences, e.g. B. depends on the ambient temperature, it is therefore a maximum diode temperature that does not lead to thermal overload of the generator. The measurement of this temperature is described in the further course of these explanations.
  • Figure 2 shows a partial representation of a known three-phase generator with a voltage regulator.
  • Figure 2a shows the axial top view and
  • Figure 2b shows a side view.
  • Figure 2a shows the axial top view
  • Figure 2b shows a side view.
  • the positive heat sink 10 which carries the respective plus diodes of the rectifier bridge, not shown, with the connections B +, W and DF can be seen in an axial plan view.
  • the positive heat sink 10 is coupled via the connection plate 11 to the negative heat sink 12, which contains the negative diodes.
  • the voltage regulator 13 is fastened with its housing 14 to a generator component, in the exemplary embodiment on the minus heat sink 12 of the rectifier, not shown. A direct coupling of the minus heat sink 12 to the housing 14 of the voltage regulator 13 is thereby achieved.
  • the circuit located in the controller housing 14 contains a temperature measuring circuit 15, not shown in the exemplary embodiment, which measures the housing temperature and, with the good thermal coupling provided, therefore also measures the temperature of the minus heat sink 12 with almost no errors.
  • the brush holder 16 is fastened on the connection plate 11, but it can also be fastened at another location, for example on the minus heat sink 12.
  • the generator output voltage is regulated with a voltage regulator 13, which is connected to the three-phase generator 17 via the brush holder 16.
  • the generator 17, with the terminals D +, B +, DF and D-, the on-board electrical system 18 and the brush holder 16 are constructed in the usual way and will not be described in more detail here.
  • the voltage regulator 13 with the output terminals D +, DF and D- contains a generally customary switching element, for example a switching transistor 19 with a diode 20 connected in parallel, which is connected between the regulator terminals DF and D- and a freewheeling diode 21 which lies between DF and B + . Furthermore, the voltage regulator 13 contains a circuit arrangement 22, not shown, which is connected between the terminals D +, DF and D- and to the base of the transistor 18 and its collector.
  • This circuit arrangement 22 contains the temperature measuring circuit 15, which measures the housing temperature of the voltage regulator 13.
  • This circuit arrangement 22 can also include further additional functions, for example an error display option, a device for evaluating motor functions, and a temperature sensor can also be provided on the battery, the output signal of which is supplied to the circuit arrangement 21.
  • the voltage regulator 13 with the circuit 21 containing the temperature measuring circuit 15 can also be part of a generator with controlled rectifiers, for example thyristors. For example, it can be designed in a monolithic design.
  • such a voltage regulator can be attached directly to the generator with an internal temperature measuring element.
  • the generator output current is reduced directly when the temperature detected by the temperature measuring circuit contained in the voltage regulator exceeds a predeterminable value.
